Python 中request以json形式发送post请求

一个http请求包括三个部分，为别为请求行，请求报头，消息主体，类似以下这样：

• 请求行
• 请求报头
• 消息主体

以json串提交数据，编码格式：application/json， 可以将一json串传给requests.post()的data参数

=== 案例一 ====

import requests
import json
headers = {
"Content-Type": "application/json; charset=UTF-8",
"Referer": "http://jinbao.pinduoduo.com/index?page=5",
"User-Agent": "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.87 Safari/537.36",
}
url = "http://jinbao.pinduoduo.com/network/api/common/goodsList"
pyload = {"keyword": "", "sortType": 0, "withCoupon": 0, "categoryId": 16, "pageNumber": 1, "pageSize": 60}
response = requests.post(url, data=json.dumps(pyload), headers=headers).text
print(response）

=== 案例二 ====

import requests
import json

MSISDN = input('请输入msisdn: ')

headers = {
    "Content-Type": "application/json",
    "Postman-Token": "255b9cb2-36a4-46b1-a341-2a147c94788a",
    "cache-control": "no-cache",
    }
url = "http://operator-xxxxxx"
payload = {"msisdn":MSISDN}
response = requests.post(url, data=json.dumps(payload), headers=headers)

print(response.text)
